Is it real to get money back after SCAM?

No. They can't pay even face-value to everyone because of commission fee. But sometimes administrators promis «to repay debts» from restart of the project. Restart is either way to make some more money, or nonsense. Financial pyramid accumulate debts itself with not a single thing to spare. And there is a restart, it will collapse even faster. If you lose your money don't invest again, just ignore it. Because in restart you will lose even more.
